Kost Tire & Auto Service

I had a battery in my car that was under warranty, which was bought at a nearby auto parts store. I had taken my car in for an alignment, that is it. Kost stated I needed a new battery, which the battery that was in there was fine and still under warranty. They went over to get the replacement battery at the nearby auto parts store which was under warranty, and installed it in my car. I was then charged $67 dollars for what should have been a free installation for a under warranty battery. If I knew they were going to charge me, I would have just let the auto parts store do it for free. I feel that because I am an elderly female, they took advantage and just wanted to charge me for something not needed.
